My 94 z8 Camaro shut off and wont even crank now??? Please help!!!?

try this out. see if your car is equiped with a fuel pump shut off switch. this is a safety feature, that will only let the car start, and it shuts it back off because this switch is tripped. it is usually undewr the dash on the passenger side of the vehicle. its job is to keep the car from catching on fire in case of an accident, and doubles a sa theft deterant system. and it cost nothing to reset. just push the button on the top to reset. good luck.
